This Biturbo costs me 2 euros ($2.90) ! I purchased it at a swapmeet in Holland. Made by Grani & Partners for the Italian collection "La Maserati - I modelli che hanno fatto la storia (http://www.database43.com/main/index.php?option=com_wrapper&Itemid=355)" (the models which make the history).

Sweet, especially for just $3!

It's a beauty! I wish Kyosho would made a similar series in 1/64.
